Hi, thank you for authoring eukleides! I am maintaining eukleides as a Debian package, and chances are that I will no longer be able to maintain it, when the compiler gcc-15 will enter debian/testing (it is currently part of debian/experimental), which should occur in a few months.
Here is a recipe to test eukleides' source conformance with gcc-15:
- install gcc-15
- modify build/Makefile : replace the line "CC = gcc" by "CC ?= gcc"
- set the environment variable CC to gcc-15: in a bash shell that means:
"export CC=gcc-15"
- run the command "make"
I tried to fix eukleides' source, in order to comply with the stricter
requirements which come with gcc-15 : this compiler checks the profile
of functions in a very picky way, and raises errors when extra arguments
are used during a call.
Here is a typical error:
----------------------8<---------------------------------
../src/common/core.c: In function ‘exec_itable’:
../src/common/core.c:215:20: error: too many arguments to function
‘itable.cur->func’; expected 0, have 1
215 | (itable.cur->func)(itable.cur->param);
| ~~~~~~~~~~~^~~~~~~ ~~~~~~~~~~~~~~~~~
In file included from ../src/common/core.c:23:
../src/common/core.h:44:12: note: declared here
44 | void (*func)();
| ^~~~
----------------------8<---------------------------------
I could not fix all the errors, by a naive replacement of function
declarations with a void sequence of parameter, by replacing () or (void)
by (_param). Such a naive replacement works in some places, but in other
places, it causes circular incoherences, which I could not understand
easily.
Please can you give a try? There is no hurry, but gcc-15 will replace
former versions of the compiler some day.
Thank you in advance.
Best regards, Georges.
